<div><div class="section"><h4 class="sectiontitle">现象描述</h4><p>数据盘恢复到新位置后，新位置的虚拟机磁盘数量比恢复前多。</p>
</div>
<div class="section"><h4 class="sectiontitle">可能原因</h4><div class="p">磁盘恢复过程中<span>OceanProtect</span>会判断目标虚拟机上是否存在原磁盘，如果不存在会重新创建磁盘进行恢复。在以下场景会判断为需要重新创建磁盘：<ul><li>原磁盘已被删除。</li><li>原磁盘扩容过。</li><li>原磁盘更换过数据存储。</li><li>原磁盘ID变更过。</li><li>原磁盘不在目标虚拟机上。在以下场景会判断目标虚拟机上存在原磁盘：<ul><li>对于FusionCompute 6.3之前版本：<ul><li>如果副本磁盘和目标磁盘槽位号都为1且都为IDE类型，则认为副本磁盘存在目标虚拟机上。</li><li>如果副本磁盘和目标磁盘的URN（Uniform Resource Name，例如：urn:sites:1:volumes:78）相等且槽位号都不为1 ，则认为副本磁盘存在目标虚拟机上。</li></ul>
</li><li>对于FusionCompute 6.3及后续版本：<ul><li>如果副本磁盘和目标磁盘都是系统盘，则认为副本磁盘存在目标虚拟机上。</li><li>如果副本磁盘和目标磁盘的URN（例如：urn:sites:1:volumes:78）相等且都不是系统盘，则认为副本磁盘存在目标虚拟机上。</li></ul>
</li></ul>

<div class="section"><h4 class="sectiontitle">处理步骤</h4><p>恢复至新位置的磁盘会带“_RESTORE”后缀，恢复后的磁盘需新增分区并重新挂载。如需解绑定多余的磁盘，可参考以下操作执行。以下操作以FusionCompute 8.1.1版本为例进行说明。</p>
